This is a short story based loosely based on actual events. All people are over 18.
------------------------------------
For those of you who haven't read any of my other stories I have been married to Ruth for the last 10 years and I have a step daughter called Joanne. Ruth is a very hot 5ft 6" brunette who regularly goes to the gym to keep fit. Her boobs are just about the perfect size and her ass is to die for. Joanne takes after her mum. She's about the same height with a stunning figure and has slightly bigger boobs and long light brown hair. I'm 6ft with short fair hair and keep in pretty decent shape myself, but its more from walking and hiking than the gym.
------------------------------------
It was Monday morning and I was supposed to be heading to work but I was running behind. Ruth had already left and I just couldn't get motivated to get moving.
I had run my own business for several years and it was making a decent income but some days I just wished I could retire and forget about it all.
I had got up earlier to get a cup of coffee to try and give myself a kickstart and was sitting in my office browsing through emails on my computer as I drank it. After a few minutes I started to lose interest and my mind though back to the weekend.
Ruth and I have a very healthy sex life and we had a lot of fun on Saturday afternoon. The more I thought about what we had got up to the more I got turned on.
I stuck my hand down my boxer shorts and took my hard cock out giving it a long slow wank before opening a private browser on my computer and looking up my favourite porn site.
The page came up with a lot of different genres of porn but I was drawn to one about a step daughter. Mainly because the actress looked exactly like my step daughter Joanne. It was such a strong likeness I wasn't convinced it wasn't actually her!!!
I clicked on the file and turned the sound up as I watched Joannes look-a-like getting ready to meet her boyfriend. She pulled on stockings and a black thong and garter belt before putting on a black lace bra and a very short, tight, pink mini dress which showed off her long legs and generous cleavage.
My cock was getting harder the more I watched, picturing Joanne instead of the actress.
I didn't want to cum too soon so I watched on while I wanked my cock slowly.
A few minutes into the scene her boyfriend arrived and I could see his eyes light up as he looked at his stunning girlfriend, picturing what he was going to be doing to her later.
As they started kissing passionately my phone started ringing with a call from one of my biggest customers.
Annoyed that I wasn't going to see what happened I paused the video and answered the phone to see what they needed.
"Stacey, how are you?" I asked.
"I'm great thanks Pete, just a couple of things I would need sorted if you have time this afternoon?" she replied.
"Thats no problem at all. I can be in the office for 12.00pm if that suits?" I replied.
"That will do well. I'm looking forward to seeing you again." replied Stacey.
"You too, see you then." I said, meaning it. Not only was Stacey a good customer she was hot as fuck... Which wasn't doing much to help my current hard on.
I decided to leave the video for now even though I really wanted some release. I needed to get a shower and get my things ready for work.
I left my office and quickly jumped into the shower.
A few minutes later, feeling a bit more awake and certainly fresher, I went to grab an energy bar and another cup of coffee from the kitchen.
I hadn't put any clothes on when I got out of the shower as we weren't overlooked and Ruth was already away to work.
I thought more about Joanne and the video as I waited for the coffee machine to finish before grabbing the coffee in one hand and energy bar in the other, heading to our bedroom to get dressed.
Just as I walked into our large hallway the front door opened and Joanne walked in...
I didn't know what to do or where to look, I was standing completely naked with an energy bar in one hand and coffee in the other. I couldn't cover my semi with no hands free.
"Oh sorry..." gasped Joanne, looking down at my growing erection. "I just came to borrow some of mums clothes, she said I could just call round."
"No... eh... problem." I stuttered, my face growing hot as Joanne continued to stare at my rapidly hardening cock.
"Sorry I was just in the shower and I didn't know you were coming." I said, feeling like I really needed to explain.
"Thats no problem. It's a nice surprise." replied Joanne with a slight smile on her lips. "I would ask if you're pleased to see me but I think that's pretty obvious. Can I just go and grab them from your bedroom?"
"Of course." I replied, pointing down towards our bedroom which made my cock swing in that direction as well. That didn't go unnoticed by Joanne.
"Thanks," she replied as she walked past me "I'll only be a minute.'
I watched her mini skirt covered ass as it walked down the corridor in front of me. She had on high heels and a low cut top as well to show off her figure. I wasn't sure where she was going tonight but I knew she hadn't had a boyfriend in months.
I didn't know what to do so just stood in my own hall, bollock naked waiting on her coming back so I could go and get dressed.
"Pete." she called, "can you come here a minute and give me your opinion?"
I walked down to the bedroom, my hard cock bouncing in front of me, wondering what she wanted my opinion on.
"I have a hot date this evening and I wanted something sexy for it." she said holding up a couple of Ruths more daring dresses. "Which one do you prefer?"
I was torn as to what to do. I set my coffee down on the bedside table but Joanne was standing in front of the wardrobes where all my clothes were.
"So which one then?" she asked, holding them up against her. "Should I try them on to give you a better idea?"
Not waiting for an answer she set the dresses down on the bed and proceeded to undo the zip on her miniskirt before letting it drop to the floor. She was wearing a black lace thong, not unlike the actress in the video. She then pulled her top over her head to reveal a matching back lace bra.
"Can... I.... just.... get... some.... eh.... boxers" I stuttered, trying hard not to perve over my step daughter.
"Don't worry about it," replied Joanne, looking down at my hard cock, "I like seeing the effect I have on a man. It's been a while since I've seen a nice hard cock. I'm not sure I've ever seen one that big though."
She lifted the first dress and stepped into it before pulling it up. It was a snug fit on her, especially around her boobs. Ruth and Joanne are about the same size but Joanne as bigger boobs and Ruth has a firmer ass.
"What do you think?" she asked, giving me a twirl. "Would you want to peel this off me and fuck me if you were my date?"
I think my cock was speaking for me at that stage and I was stunned into silence thinking of peeling that dress off her and ramming my hard cock deep inside her tight pussy... all I could manage was a nod of my head.
